ConclusionsConclusions
• Procedure has migrated to truly percutaneous approach, with the majority of cases done under local anesthesia without CPS
• High procedural success rate
• Adjudicated 18‐Fr. S&E trial demonstrates both safety and efficacy with a concomitant improvement in NYHA‐FC in high risk patients
• No valve migration or frame fractures
• Published and ongoing studies confirm transferable learning curve
• Expanded indication beyond high risk patients must be based on improved QOL and durability of the valve
![Page 31: Update on the CoreValve Experience · Update on the CoreValve Experience Eberhard Grube HELIOS Klinikum Siegburg, Germany Instituto Dante Pazzanese de Cardiología, São Paulo, Brazil](https://reader030.fdocuments.net/reader030/viewer/2022040318/5e35dfc963f83667da27fb87/html5/thumbnails/31.jpg)
Siegburg
• The initial early experience with CoreValve 18 French TAVI is encouraging.
• Longer term follow‐up data will address appropriate patient population for transcatheter valve use.
• High technical success rate with TAVI
• No evidence of frame migration
• 18 French Safety & Efficacy Data (adjudicated)
• 81% 1 year freedom from cardiac death
• 92% 1 year freedom from stroke
• 80% of patients experienced at least 1 NYHA class improvement
• 18 French Safety & Efficacy data is supported by other publishedand ongoing studies and registries.
